So I'm still learning about texturing in blender. Then after googling around i found about shader editor and uv editor. When i first open shader editor to make material the node show up okay. Then after that i go to uv editor to aligning the textures to my object. But, when i go back to shader editor to messin around with roughness and heightmap, the nodes that's there before is gone and just show up blank like this
I think that you set up your nodes for the brick material, yet because you are in object mode, you have the default material showing up to be edited, not the brick. Change which material is to be edited at the top of the shader editor window.
